Unique ID property in CoreMidi

MIOS programming (C)
1

Hello again,

one short question (did some searching, not finding anything, although I am pretty sure it must be around): When I talk to my Core32 from my computer (Mac), I can get something which is called “unique id” or to be specific, the kMIDIPropertyUniqueID. Is that in any way related to the device id or anything? Can it be set from MIOS32? This property is only available from CoreMidi (OS X specific).

Thanks, wackazong.

I think the basic question here is; How is CoreAudio’s kMIDIPropertyUniqueID generated?

The unique ID isn’t explicitly forwarded by MIOS32, the calculation is OS dependent (e.g. by name, vendor/product/device ID, USB node, etc…)
